text: You have already got half of your problem solved. You recognize that some of your life's choices were bad. Now to solved the other half of your problem, you have to STOP and THINK before you act. Don't just cater to your every whim, think about the consequenses of your action,and then decide whether you want to go with the  choice or not. If you decide the choice is bad,you'll have to muster all the will power you got to refrain from taking this course of action.At first, conditioning yourself to make the right choices will be hard, but after you do it more and more, it will become the natural thing to do. Good luck.
